  Incidentally, multilayer ceramic capacitors may be affected by electrostatic discharge. When static electricity flows through the multilayer ceramic capacitor, the internal electrode generates heat due to the resistance of the internal electrode. For this reason, there is a possibility that the internal electrodes are melted and the internal electrodes are short-circuited. When the internal electrodes are short-circuited, the terminal electrodes to which the internal electrodes are connected are short-circuited, and the multilayer ceramic capacitor does not function. Therefore, in this technical field, there is a demand for a multilayer ceramic capacitor that is less likely to cause a short circuit even when static electricity flows.

  An object of the present invention is to provide a multilayer ceramic capacitor in which a short circuit is unlikely to occur even when static electricity flows.

  A multilayer ceramic capacitor according to the present invention includes an element body formed by laminating a plurality of dielectric layers and a plurality of internal electrodes, and a first terminal electrode and a second terminal disposed on the outer surface of the element body The first capacitor part including a first internal electrode connected to the first terminal electrode and a second internal electrode connected to the second terminal electrode as a plurality of internal electrodes, A third internal electrode connected to the first terminal electrode, a fourth internal electrode connected to the second terminal electrode, a fifth internal electrode not connected to any of the first terminal electrode and the second terminal electrode; A second capacitor portion including a plurality of internal electrodes, wherein in the first capacitor portion, the first internal electrode and the second internal electrode are arranged to face each other in the stacking direction of the element body, In the capacitor section, the third internal electrode and the fourth internal electrode The five internal electrodes are arranged to form a plurality of capacitance components connected in series between the first terminal electrode and the second terminal electrode, and the combined capacitance of each capacitance component of the second capacitor portion is It is larger than the capacitance between the first internal electrode and the second internal electrode facing each other in one capacitor part.

  In the multilayer ceramic capacitor according to the present invention, the combined capacitance of the capacitive components of the second capacitor portion is larger than the capacitance between the first internal electrode and the second internal electrode facing each other in the first capacitor portion. Since static electricity tends to flow in the direction where the electrostatic capacity is larger, a plurality of capacitive components having a relatively large electrostatic capacity are formed than between the first internal electrode and the second internal electrode having a relatively small electrostatic capacity. Static electricity easily flows between the third internal electrode, the fourth internal electrode, and the fifth internal electrode. That is, static electricity hardly flows through the first capacitor part including the first internal electrode and the second internal electrode compared to the second capacitor part including the third internal electrode, the fourth internal electrode, and the fifth internal electrode. . Therefore, heat due to static electricity flowing through the first capacitor portion hardly occurs, and the possibility that the first internal electrode and the second internal electrode are melted by the heat is suppressed. Thereby, it is possible to make it difficult to cause a short circuit between the first internal electrode and the second internal electrode. Furthermore, in the second capacitor portion, a plurality of capacitance components connected in series are formed. For this reason, even when static electricity flows through the second capacitor unit, the entire second capacitor unit is not short-circuited unless all the internal electrodes forming the plurality of capacitance components are short-circuited. As described above, according to the multilayer ceramic capacitor according to the present invention, it is difficult to cause a short circuit in the first capacitor unit as compared with the second capacitor unit, and a short circuit is not generated as much as possible in the second capacitor unit as a whole. can do. As a result, it is possible to make it difficult for a short circuit to occur in the multilayer ceramic capacitor. As described above, it is possible to provide a monolithic ceramic capacitor in which a short circuit hardly occurs even when static electricity flows.

  Two second capacitor portions are arranged with the first capacitor portion sandwiched in the stacking direction, and in each second capacitor portion, the third internal electrode and the fourth internal electrode are more than the fifth internal electrode in the stacking direction. It may be arranged outside. When the electric field formed between each terminal electrode arranged on the outer surface of the element body and each internal electrode arranged in the element body is strong, electrons are likely to jump out from each terminal electrode. When electrons jump out from each terminal electrode, the jumped-out electrons are transmitted to the outer surface of the element body, which may cause surface leakage of current. According to the present invention, in each second capacitor portion arranged with the first capacitor portion sandwiched in the stacking direction, the third internal electrode and the fourth internal electrode are outside the fifth internal electrode in the stacking direction, that is, the element. It is located at the position closest to the outer surface of the body. The fourth internal electrode having a different polarity from the first terminal electrode is located farther from the first terminal electrode than the third internal electrode having the same polarity as the first terminal electrode. The third internal electrode having a different polarity from the second terminal electrode is located farther from the second terminal electrode than the fourth internal electrode having the same polarity as the second terminal electrode. As described above, since each terminal electrode and each internal electrode having different polarities are separated from each other, the electric field formed between each terminal electrode and each internal electrode is weakened, and electrons are emitted from each terminal electrode. Can be difficult. As a result, it is possible to suppress surface leakage of current that occurs when electrons that have jumped out from each terminal electrode travel along the outer surface of the element body.

  The width of the portion where the third internal electrode is connected to the first terminal electrode and the width of the portion where the fourth internal electrode is connected to the second terminal electrode are the width of the portion where the first internal electrode is connected to the first terminal electrode. It is larger than the width and larger than the width of the portion where the second internal electrode is connected to the second terminal electrode. In this case, the width of the portion where each internal electrode is connected to each terminal electrode is larger in the second capacitor portion than in the first capacitor portion. Therefore, compared with the case where the width is the same in the first capacitor portion and the second capacitor portion, the resistance of the second capacitor portion is lower than the resistance of the first capacitor portion. Static electricity is more likely to flow toward the capacitor. That is, static electricity is less likely to flow through the first capacitor portion, and as a result, a short circuit in the first capacitor portion can be more unlikely to occur.

  Of the distance between the internal electrode of the first capacitor part and the internal electrode of the second capacitor part, the distance between the internal electrodes adjacent to each other in the stacking direction is the stacking direction of the internal electrodes of the second capacitor part. It may be larger than the interval between adjacent internal electrodes facing each other. In this case, since the first capacitor part and the second capacitor part are separated from each other than the interval between the internal electrodes of the second capacitor part, static electricity that has flowed to the second capacitor part is difficult to flow into the first capacitor part. Therefore, it is possible to make the short circuit in the first capacitor portion less likely to occur.

  Among the internal electrodes of the first capacitor part and the internal electrode of the second capacitor part, the dielectric constant of the dielectric layer between the internal electrodes that are adjacent to each other in the stacking direction is opposite to that of the second capacitor part. Of the internal electrodes, the dielectric constant of the dielectric layer between the internal electrodes adjacent to each other in the stacking direction may be lower. In this case, since the dielectric constant of the dielectric layer between the first capacitor part and the second capacitor part is lower than the dielectric constant of the dielectric layer between the internal electrodes of the second capacitor part, it flowed to the second capacitor part. Static electricity hardly flows into the first capacitor section. Therefore, it is possible to make the short circuit in the first capacitor portion less likely to occur.

  The element body, as an outer surface, connects the first side surface and the second side surface facing each other in the first direction orthogonal to the stacking direction, the first side surface and the second side surface, and is orthogonal to the stacking direction and the first direction. The first terminal electrode has a first end face and a second end face facing each other in the second direction, and the first terminal electrode is located on the first end face side of the first end face and on the first end face side of the first side face. A second portion, a third portion located on the first end surface side portion of the second side surface, and the second terminal electrode includes a fourth portion located on the entire second end surface and a first portion on the first side surface. A fifth portion located on the second end surface side and a sixth portion located on the second end surface side portion on the second side surface; the third internal electrode comprises a first end surface and a first side surface on the second side surface; It is exposed to a portion on one end surface side and a portion on the first end surface side in the second side surface, and the first portion and the second portion And the fourth internal electrode is exposed to the second end surface, the second end surface side portion of the first side surface, and the second end surface side portion of the second side surface, respectively. And you may each be connected to the 4th part, the 5th part, and the 6th part. The lower the resistance to static electricity, the less heat is generated by static electricity. In the present invention, the third internal electrode of the second capacitor portion is exposed not only on the first end surface of the element body but also on the first end surface side of each of the first side surface and the second side surface, and the first terminal The first part, the second part, and the third part of the electrode are connected to each other. The fourth internal electrode of the second capacitor part is exposed not only on the second end face of the element body but also on the second end face side of each of the first side face and the second side face, and the fourth inner electrode of the second terminal electrode. It is connected to the part, the fifth part, and the sixth part. Therefore, the third internal electrode and the fourth internal electrode are wider at the connection portion with each terminal electrode than when exposed only on the first end face or the second end face of the element body, and the resistance to static electricity is low. ing. Therefore, the amount of heat generated when static electricity flows through each internal electrode can be reduced. Further, the resistance of the third internal electrode and the fourth internal electrode included in the second capacitor part becomes low, so that static electricity can easily flow through the second capacitor part. That is, static electricity is less likely to flow through the first capacitor portion, and a short circuit in the first capacitor portion is less likely to occur.

  The thickness of each internal electrode of the second capacitor unit in the stacking direction is larger than the thickness of each internal electrode of the first capacitor unit in the stacking direction. In this case, since the second capacitor portion has a lower resistance than the first capacitor portion because the thickness in the stacking direction of each internal electrode included therein is larger, static electricity flows more easily through the second capacitor portion. That is, static electricity is less likely to flow through the first capacitor portion, and a short circuit in the first capacitor portion is less likely to occur.

  According to the present invention, it is possible to provide a multilayer ceramic capacitor in which a short circuit hardly occurs even when static electricity flows.

And an electrode portion 6b (sixth portion) located at the portion on the second end surface 3b side.

  The first terminal electrode 5 and the second terminal electrode 6 have a baking layer 7 and plating layers 8 and 9.

The first terminal electrode 5 and the second terminal electrode 6 have different polarities on the outer surface of the element body 3 and are electrically insulated.

  The element body 3 has a first capacitor part C1 and a second capacitor part C2. Two second capacitor portions C2 are arranged with the first capacitor portion C1 sandwiched in the stacking direction. That is, the element body 3 includes a second capacitor portion C2 on the first main surface 3e side of the element body 3, and a second capacitor portion C2 on the second main surface 3f side of the element body 3. Each second capacitor part C <b> 2 is located closer to the outer surface of the element body 3 than the first capacitor part C <b> 1 in the element body 3.

  The 1st capacitor | condenser part C1 contains the internal electrode 11 (1st internal electrode) and the internal electrode 12 (2nd internal electrode) as several internal electrodes. The internal electrode 11 and the internal electrode 12 are arranged at different positions in the stacking direction. The internal electrode 11 and the internal electrode 12 are disposed adjacent to each other in the stacking direction, and face each other with the dielectric layer 4 interposed therebetween.

  The second capacitor unit C2 includes an internal electrode 13 (third internal electrode), an internal electrode 14 (fourth internal electrode), and an internal electrode 15 (fifth internal electrode) as a plurality of internal electrodes. The internal electrode 13 and the internal electrode 14 are spaced apart from each other in the opposing direction of the first end surface 3a and the second end surface 3b at the same position in the stacking direction. The internal electrode 15 is disposed at a position different from the internal electrode 13 and the internal electrode 14 in the stacking direction. The internal electrode 13, the internal electrode 14, and the internal electrode 15 are disposed adjacent to each other in the stacking direction and face each other with the dielectric layer 4 interposed therebetween.

  In the second capacitor portion C2 on the first main surface 3e side of the element body 3, the internal electrodes 13 and the internal electrodes 14 are closer to the first main surface 3e of the element body 3 in the stacking direction than the opposed internal electrodes 15 are. Is arranged. In the second capacitor portion C2 on the second main surface 3f side of the element body 3, the internal electrodes 13 and the internal electrodes 14 are closer to the second main surface 3f of the element body 3 in the stacking direction than the opposed internal electrodes 15 are. Is arranged. Thus, in each 2nd capacitor | condenser part C2, the internal electrode 13 and the internal electrode 14 are arrange | positioned outside the internal electrode 15 in the lamination direction. That is, the internal electrode 13 and the internal electrode 14 are disposed closest to the outer surface of the element body 3 among the internal electrodes 11 to 15.

  Since the internal electrode 13 is not connected to the second terminal electrode 6, the internal electrode 13 is located farther from the second terminal electrode 6 than the internal electrode 14 connected to the second terminal electrode 6. Since the internal electrode 14 is not connected to the first terminal electrode 5, the internal electrode 14 is located farther from the first terminal electrode 5 than the internal electrode 13 connected to the first terminal electrode 5.

  Of the internal electrodes included in the first capacitor part C1, the internal electrode 11 or the internal electrode 12 disposed closest to the outer surface of the element body 3 in the stacking direction is disposed adjacent to the internal electrode 15 in the stacking direction. Has been. The internal electrode 11 or the internal electrode 12 and the internal electrode 15 are opposed to each other with the dielectric layer 4 interposed therebetween.

  In the present embodiment, the interval between the internal electrode 11 or the internal electrode 12 and the internal electrode 15 in the stacking direction is substantially equal to the interval between the internal electrode 13 and the internal electrode 14 and the internal electrode 15 in the stacking direction. For this reason, the thickness in the stacking direction of the dielectric layer 4 sandwiched between the internal electrode 11 or the internal electrode 12 and the internal electrode 15 adjacent in the stacking direction, and the internal electrode 13 and the internal electrode 14 adjacent in the stacking direction and the internal The dielectric layers 4 sandwiched between the electrodes 15 have substantially the same thickness in the stacking direction. Note that the dielectric constant of the dielectric layer 4 is substantially the same in any layer.

  Each internal electrode 11-15 consists of an electroconductive material (for example, Ni or Cu etc.) normally used as an internal electrode of a laminated type electric element. Each internal electrode 11-15 is comprised as a sintered compact of the electrically conductive paste containing the said electrically conductive material.

  FIG. 3A shows the internal electrode 11 included in the first capacitor portion C1. As shown in FIG. 3A, the internal electrode 11 has a substantially rectangular shape in plan view. In the present specification, the substantially rectangular shape includes not only a rectangular shape but also a shape in which corners of a rectangular shape are rounded, for example. One end of the internal electrode 11 is exposed at the first end surface 3a of the element body 3, and is directly connected to the first terminal electrode 5 at the first end surface 3a. Thereby, the internal electrode 11 is electrically connected to the first terminal electrode 5. The other end of the internal electrode 11 is located in the element body 3 and is not exposed to the second end face 3b. That is, the internal electrode 11 is not connected to the second terminal electrode 6. Therefore, the internal electrode 11 has the same polarity as the first terminal electrode 5.

  FIG. 3B shows the internal electrode 12 included in the first capacitor portion C1. As shown in FIG. 3B, the internal electrode 12 has a substantially rectangular shape in plan view. One end of the internal electrode 12 is exposed at the second end surface 3b of the element body 3, and is directly connected to the second terminal electrode 6 at the second end surface 3b. Thereby, the internal electrode 12 is electrically connected to the second terminal electrode 6. The other end of the internal electrode 12 is located in the element body 3 and is not exposed to the first end surface 3a. That is, the internal electrode 12 is not connected to the first terminal electrode 5. Therefore, the internal electrode 12 has the same polarity as the second terminal electrode 6.

The width A ₁₁ of the portion where the internal electrode 11 is connected to the first terminal electrode 5 is substantially equal to the width A _{12 of the} portion where the internal electrode 12 is connected to the second terminal electrode 6. The internal electrode 11 and the internal electrode 12 are positioned so that their surfaces overlap each other when viewed from the stacking direction. Since the internal electrode 11 has the same polarity as the first terminal electrode 5 and the internal electrode 12 has the same polarity as the second terminal electrode 6, the internal electrode 11 and the internal electrode 12 have different polarities. Thus it is the one internal electrode 11 and one of the internal electrodes 12 in the area facing the capacitive component C1 ₁ is formed (see FIG. 2).

  FIG. 4A shows the internal electrode 13 and the internal electrode 14 included in the second capacitor unit C2. As shown to (a) of FIG. 4, the internal electrode 13 and the internal electrode 14 are exhibiting the substantially rectangular shape by planar view.

  One end of the internal electrode 13 is exposed on the first end surface 3a of the element body 3, and is directly connected to the first terminal electrode 5 on the first end surface 3a. Thereby, the internal electrode 13 is electrically connected to the first terminal electrode 5. The other end portion of the internal electrode 13 is located apart from the internal electrode 14 in the element body 3 and is not exposed to the second end surface 3b. That is, the internal electrode 13 is not connected to the second terminal electrode 6. Therefore, the internal electrode 13 has the same polarity as the first terminal electrode 5.

  One end of the internal electrode 14 is exposed at the second end surface 3b of the element body 3, and is directly connected to the second terminal electrode 6 at the second end surface 3b. Thereby, the internal electrode 14 is electrically connected to the second terminal electrode 6. The other end portion of the internal electrode 14 is located apart from the internal electrode 13 in the element body 3 and is not exposed to the first end surface 3a. That is, the internal electrode 14 is not connected to the first terminal electrode 5. Therefore, the internal electrode 14 has the same polarity as the second terminal electrode 6.

  FIG. 4B shows the internal electrode 15 included in the second capacitor unit C2. As shown in FIG. 4B, the internal electrode 15 has a substantially rectangular shape in plan view. Both end portions of the internal electrode 15 are located in the element body 3 and are not exposed to the first end surface 3a and the second end surface 3b. That is, the internal electrode 15 is not connected to either the first terminal electrode 5 or the second terminal electrode 6.

The width A _{21 of the} portion where the internal electrode 13 is connected to the first terminal electrode 5, the width A _{22 of the} portion where the internal electrode 14 is connected to the second terminal electrode 6, and the first side surface 3 c and the second side surface 3 d the width a ₂₃ of the internal electrodes 15 in the X direction which is the opposite direction are both substantially equal. The width A ₂₃ is the same width in the X direction as the width A ₂₁ and the width A ₂₂ . The internal electrode 13 and the internal electrode 14 and the internal electrode 15 are positioned so that their surfaces overlap each other when viewed from the stacking direction.

The internal electrode 13 and the internal electrode 14 share the internal electrode 15. In the region where the internal electrode 13 and internal electrode 15 are opposed to each other is capacitive component C2 ₁ is formed, in the region where the internal electrode 14 and the internal electrode 15 are opposed to each capacitance component C2 ₂ is formed (see FIG. 2 ). That is, the internal electrode 15 is opposed to each of the internal electrode 13 and the internal electrode 14 and is connected in series between the first terminal electrode 5 and the second terminal electrode 6 (in this embodiment, two ) Capacitance components C2 ₁ and C2 ₂ are formed.

Capacitance between the inner electrode 15 and internal electrode 13 opposed to each other, i.e. the capacitance component C2 _1, the electrostatic capacitance between the inner electrode 15 and the internal electrode 14 facing each other, i.e., the capacitive component C2 ₂ resultant capacitance, the electrostatic capacitance between the inner electrode 11 and the internal electrode 12, i.e. greater than the capacitance component C1 _1. In other words, a capacitance component C2 ₁ formed by one internal electrode 15 and one internal electrode 13, and a capacitance component C2 ₁ connected in series with the capacitance component C2 ₁ and formed by one internal electrode 15 and one internal electrode 14. that the combined capacitance of the capacitance component C2 ₂ is greater than the capacitance of the capacitance component C1 ₁ in the first capacitor portion C1.

The combined capacity of the capacitive components C2 ₁ and C2 ₂ is, for example, about ₂ to 40 μF. On the other hand, the capacitance of the capacitive component C11 is, for example, about ₁ to 20 μF. Therefore, the ratio between the combined capacitance of the capacitive components C2 ₁ and C2 ₂ and the electrostatic capacitance of the capacitive component C1 ₁ is, for example, about 10: 1 to 10: 9.

As described above, according to the multilayer ceramic capacitor 1 according to the present embodiment, the combined capacitance of the capacitance components C2 ₁ and C2 ₂ of the second capacitor portion C2 is equal to the internal electrode 11 and the internal electrode 12 facing each other of the first capacitor portion C1. greater than the capacitance of the capacitance component C1 ₁ between the. Since static electricity tends to flow toward the larger electrostatic capacity, a plurality of capacitive components C2 ₁ and C2 ₂ having a relatively large electrostatic capacity than between the internal electrode 11 and the internal electrode 12 having a relatively small electrostatic capacity. The static electricity tends to flow between the internal electrodes 13 to 15 forming the. That is, static electricity hardly flows through the first capacitor part C1 including the internal electrodes 11 and 12 as compared with the second capacitor part C2 including the internal electrodes 13 to 15. Therefore, heat due to static electricity flowing through the first capacitor portion C1 hardly occurs, and the possibility that the internal electrodes 11 and 12 are melted by the heat is suppressed. Further, in the second capacitor unit C2, a plurality of capacitance components C2 ₁ and C2 ₂ connected in series are formed. For this reason, even when static electricity flows through the second capacitor unit C2, the entire second capacitor unit C2 is not short-circuited unless all the internal electrodes forming the plurality of capacitance components C2 ₁ and C2 ₂ are short-circuited. As described above, according to the multilayer ceramic capacitor 1, it is difficult to cause a short circuit in the first capacitor unit C1 as compared with the second capacitor unit C2, and a short circuit as a whole does not occur in the second capacitor unit C2. can do. As a result, a short circuit in the multilayer ceramic capacitor 1 can be made difficult to occur. From the above, it is possible to provide the monolithic ceramic capacitor 1 that is less likely to cause a short circuit even when static electricity flows.

  When the electric field formed between each terminal electrode arranged on the outer surface of the element body and each internal electrode arranged in the element body is strong, electrons are likely to jump out from each terminal electrode. When electrons jump out from each terminal electrode, the jumped-out electrons are transmitted to the outer surface of the element body, which may cause surface leakage of current. According to the multilayer ceramic capacitor 1 according to the present embodiment, in each second capacitor portion C2 arranged with the first capacitor portion C1 sandwiched in the stacking direction, the internal electrode 13 and the internal electrode 14 are internal electrodes 15 in the stacking direction. It is arranged on the outer side, that is, the position closest to the outer surface of the element body 3. The internal electrode 14 having a different polarity from the first terminal electrode 5 is located farther from the first terminal electrode 5 than the internal electrode 13 having the same polarity as the first terminal electrode 5. The internal electrode 13 having a different polarity from the second terminal electrode 6 is located farther from the second terminal electrode 6 than the internal electrode 16 having the same polarity as the second terminal electrode 6. Thus, since each terminal electrode 5 and 6 and each internal electrode 13 and 14 which are mutually different polarities are separated, it is formed between each terminal electrode 5 and 6 and each internal electrode 13 and 14. Therefore, it is possible to make it difficult for electrons to jump out from the terminal electrodes 5 and 6. As a result, it is possible to suppress surface leakage of current that occurs when electrons that have jumped out from the terminal electrodes 5 and 6 travel along the outer surface of the element body 3.

Next, a multilayer ceramic capacitor according to the second embodiment will be described with reference to FIGS. FIG. 5 is a plan view showing internal electrodes included in the first capacitor portion of the multilayer ceramic capacitor according to the second embodiment. FIG. 6 is a plan view showing internal electrodes included in the second capacitor portion of the multilayer ceramic capacitor according to the second embodiment.

  Although the multilayer ceramic capacitor according to the present embodiment is not illustrated, the multilayer body 3 and the first terminal electrode 5 disposed on the outer surface of the multilayer body 3, as in the multilayer ceramic capacitor 1 according to the first embodiment, and And a second terminal electrode 6. The element body 3 has a first capacitor part C1 and a second capacitor part C2.

The multilayer ceramic capacitor according to this embodiment is different from the multilayer ceramic capacitor 1 according to the first embodiment in that the width A of the portion where the internal electrodes 11 and 12 are connected to the terminal electrodes 5 and 6 in the first capacitor portion C1. _11, the size of _{a 12.} Hereinafter, a specific description will be given with reference to FIGS. 5 and 6.

5A shows the internal electrode 11 included in the first capacitor unit C1, and FIG. 5B shows the internal electrode 12 included in the first capacitor unit C1. As shown in FIGS. 5A and 5B, the width A ₁₁ of the portion where the internal electrode 11 is connected to the terminal electrode 5 is the width A of the portion where the internal electrode 12 is connected to the second terminal electrode 6. _It is approximately equal to ₁₂ . These widths _{A 11} and the width _{A 12} according to the present embodiment is smaller than the width _{A 11} and the width _{A 12} according to the first embodiment.

6A shows the internal electrode 13 and the internal electrode 14 included in the second capacitor unit C2, and FIG. 6B shows the internal electrode 15 included in the second capacitor unit C2. As shown in FIGS. 6A and 6B, the width A _{21 of the} portion where the internal electrode 13 is connected to the first terminal electrode 5 and the portion of the portion where the internal electrode 14 is connected to the second terminal electrode 6. The width A ₂₂ is substantially equal to the width A ₂₃ of the internal electrode 15 in the X direction. These widths _{A 21} according to the present embodiment, the width _{A 22} and the width _{A 23,} the width _{A 21} according to the first embodiment, substantially equal to the width _{A 22} and the width _{A 23,.}

That is, in this embodiment, the width A _{21 of} the portion where the internal electrode 13 in the second capacitor portion C2 is connected to the first terminal electrode 5, and the internal electrode 14 in the second capacitor portion C2 is connected to the second terminal electrode 6. width a ₂₂ of the portion is larger than the width a ₁₁ of the portion internal electrode 11 in the first capacitor portion C1 is connected to the first terminal electrode 5, and the internal electrode 12 in the first capacitor portion C1 is the second terminal greater than the width a ₁₂ of the portion connected to the electrode 6.

  Therefore, according to the multilayer ceramic capacitor according to the present embodiment, the width of the portion where each internal electrode is connected to each terminal electrode is larger in the second capacitor portion C2 than in the first capacitor portion C1. Therefore, for example, the resistance of the second capacitor unit C2 is lower than the resistance of the first capacitor unit C1, compared to the case where the width is the same between the first capacitor unit C1 and the second capacitor unit C2. Static electricity flows more easily in the second capacitor part C2 than in the part C1. That is, static electricity is less likely to flow through the first capacitor unit C1, and as a result, a short circuit in the first capacitor unit C1 can be more unlikely to occur.

(Third embodiment)
Next, a multilayer ceramic capacitor according to a third embodiment will be described with reference to FIG. FIG. 7 is a cross-sectional view showing the multilayer ceramic capacitor according to the third embodiment. FIG. 7 corresponds to FIG. 2 in the first embodiment.

  As shown in FIG. 7, the multilayer ceramic capacitor 1 </ b> B according to the present embodiment is the same as the multilayer ceramic capacitor 1 according to the first embodiment, and the first terminal electrode disposed on the outer surface of the base body 3. 5 and the second terminal electrode 6. The element body 3 has a first capacitor part C1 and a second capacitor part C2.

  The multilayer ceramic capacitor 1B according to this embodiment is different from the multilayer ceramic capacitor 1 according to the first embodiment in that it has the following characteristics regarding the distance between the first capacitor portion C1 and the second capacitor portion C2. To do.

In the laminated ceramic capacitor 1B, interval B ₂₁ where the internal electrode 11 or the internal electrode 12 and the internal electrodes 15 adjacent in the stacking direction, spacing and the internal electrodes 13 and internal electrodes 14 and the internal electrodes 15 adjacent in the stacking direction B ₂₂ Bigger than. Therefore, the thickness in the stacking direction of the dielectric layer 4 sandwiched between the internal electrode 11 or the internal electrode 12 and the internal electrode 15 adjacent in the stacking direction is the same as that of the internal electrode 13 and the internal electrode 14 adjacent in the stacking direction. It is larger than the thickness in the stacking direction of the dielectric layer 4 sandwiched between the electrodes 15.

That is, the internal electrodes 11 and 12 of the first capacitor portion C1, of the distance between the internal electrodes 13 to 15 of the second capacitor portion C2, interval B ₂₁ between the internal electrodes opposed to each other adjacently in the laminating direction, of the internal electrodes 13 to 15 of the second capacitor portion C2, greater than the distance B ₂₂ between the internal electrodes adjacent in the laminating direction to face each other. For example, interval _{B 21} whereas a 10 to 100 [mu] m, distance _{B 22} is 1 to 5 [mu] m. The ratio between the distance _{B 21} and spacing _{B 22,} for example 100: 1 to 100: 5.

  Therefore, according to the multilayer ceramic capacitor 1B according to the present embodiment, the first capacitor portion C1 and the second capacitor portion C2 are separated from each other than the interval between the internal electrodes of the second capacitor portion C2. Static electricity that has flowed through the capacitor C2 is unlikely to flow into the first capacitor C1.

(Fourth embodiment)
Next, a multilayer ceramic capacitor according to the fourth embodiment will be described with reference to FIG. FIG. 8 is a cross-sectional view showing the multilayer ceramic capacitor according to the fourth embodiment. FIG. 8 corresponds to FIG. 2 in the first embodiment.

The element body 3 has a first capacitor part C1 and a second capacitor part C2.

  The multilayer ceramic capacitor 1 </ b> C according to the present embodiment has the following characteristics regarding the dielectric constant of the dielectric layer 20 disposed between the first capacitor part C <b> 1 and the second capacitor part C <b> 2. This is different from the multilayer ceramic capacitor 1 according to one embodiment.

Lower than the rate. In contrast, the dielectric constant of the dielectric layer 21 sandwiched between the internal electrode 15 adjacent to each other in the stacking direction and the internal electrode 13 and the internal electrode 14 is the dielectric constant of the dielectric layer 20 according to the first embodiment. The same.

The dielectric constant of 20 is lower than the dielectric constant of the dielectric layer 21 between the internal electrodes adjacent to each other in the stacking direction among the internal electrodes of the second capacitor unit C2. For example, the dielectric constant of the dielectric layer 20 is 20 to 200 μF / m, whereas the dielectric constant of the dielectric layer 21 is 2000 to 10,000 μF / m. The ratio of the dielectric constant in the dielectric layer 20 to the dielectric constant in the dielectric layer 21 is, for example, 1:10 to 1: 100.

  Therefore, according to the multilayer ceramic capacitor 1C according to the present embodiment, the dielectric constant of the dielectric layer 20 between the first capacitor portion C1 and the second capacitor portion C2 is the dielectric between the internal electrodes of the second capacitor portion C2. Since the dielectric constant of the layer 21 is lower, static electricity that has flowed into the second capacitor portion C2 is less likely to flow into the first capacitor portion C1. Therefore, a short circuit in the first capacitor unit C1 can be further suppressed.

It has a rectangular shape. The second electrode portion 13b is exposed at the first end surface 3a, the first side surface 3c on the first end surface 3a side, and the second side surface 3d on the first end surface 3a side. The second electrode portion 13b is directly connected to the electrode portions 5a, 5b, 5c of the first terminal electrode 5, respectively. Thereby, the internal electrode 13 is electrically connected to the first terminal electrode 5.

Relates width in the opposing direction of the first side face 3c and a second side surface 3d, the width _{A 21} in the second electrode portion 13b is greater than the width _{D 21} of the first electrode portion 13a. As described above, the second electrode portion 13b is formed wider than the first electrode portion 13a in the facing direction of the first side surface 3c and the second side surface 3d. Thus, in this embodiment, for example, than the case where the internal electrodes 13 are connected only directly to the electrode portion 5a of the first terminal electrode 5 is exposed to the first end surface 3a of the body 3 at a constant width D _21, the internal electrodes The resistance of 13 is low.

The second electrode portion 14b is exposed at the second end surface 3b, a portion of the first side surface 3c on the second end surface 3b side, and a portion of the second side surface 3d on the second end surface 3b side. The second electrode portion 14b is directly connected to the electrode portions 6a, 6b, 6c of the second terminal electrode 6, respectively. Thereby, the internal electrode 14 is electrically connected to the second terminal electrode 6.

Relates width in the opposing direction of the first side face 3c and a second side surface 3d, the width _{A 22} in the second electrode portion 14b is greater than the width _{D 22} of the second electrode portion 14b. As described above, the second electrode portion 14b is formed wider than the first electrode portion 14a in the facing direction of the first side surface 3c and the second side surface 3d. Thus, in this embodiment, for example, than the case where the internal electrodes 14 are connected only directly to the electrode portion 6a of the second terminal electrode 6 is exposed to the second end surface 3b of the body 3 at a constant width D _22, the internal electrodes The resistance of 14 is low.

  The lower the resistance to static electricity, the less heat is generated by static electricity. In the multilayer ceramic capacitor according to the present embodiment, the internal electrode 13 of the second capacitor portion C2 is not only on the first end surface 3a of the element body 3, but also on the first end surface 3a side in each of the first side surface 3c and the second side surface 3d.

The terminal electrodes 6 are connected to the electrode portions 6a, 6b, 6c, respectively.

  Therefore, the internal electrode 13 and the internal electrode 14 are wider at the connection portions with the terminal electrodes 5 and 6 than when exposed only on the first end surface 3a or the second end surface 3b of the element body 3, and are resistant to static electricity. Resistance is low. Therefore, the amount of heat generated when static electricity flows through each internal electrode can be reduced.
